WINDOW-"sushi ianvronl 7 To all whom it may concern citizen of the United States, "residing at Oakland, in the county of Alameda,'State of California, have invented certain new and useful Improvements in Window-Shade Devices; and I do hereby declare the fol-- lowing to be a full, clear, and exact description of the inventiom such as will enable others skilled in the art to which it appertains to make and use the same;

'TlllS invention relates to window shades,

' and has for'its object the provision of a novel window shade the roller of which may be adjusted vertically upon a windowv frame wherebv air may be allowed to enter a room above the shade.

An important object is to provide a shade of this character which may be'pulled bodily downwardly and which is ret urnedto its.

. original position by spring tension when the holding catch is released.

' More specifically'the'object of the invention consists in tlie'provision'of a spring roller stationary upon a window frame and carrying vertically movable brackets sup-,

porting the shade roller.

" Another object of the invention is to pro *vide a device of this character which will be simple and inexpensive in manufacture, efficient'and durable in use, and a general improvement of the art.

'l/Vith these andother objects and advantages in. view, my invention consists in the novel construction, arrangement and combi nation of parts to be hereinafter more fully side elevation thereof, Fig. 4 is-a longitudescribed and claimed, and illustrated in the accompanying drawing in which: i i

Figure 1 is a View of a window having my device applied thereto, showing theshade roller in its lowest position, Fig. 2 is an en- 7 device, Fig. 3 is a dinal sectional view through the spring roller and its associated parts,

Fig. 5 1s a vertical sectional view through the winding drum and thefguide bracket, and Fig. 6 is adetail cross sectional view through one of the guide brackets.

Y Referring more particularly to the draw Be it known that I, FRANK W. ROWE, a ings in whichlike numerals designate corresponding part'sthroughoutthe several views,

the numeral 5 indicates a. window frame to which my device is adapted to be secured.

Securedadjacent the sides of the frame 5 are. brackets 6' adapted to-su'pport my novel springjroller designated as a whole by the numeral 7. The spring roller'comprises a tubular member 8 provided at its center with a disk 9 secured therein and having reduced lateral extensions 10 provided with holes for a purpose to be described. The outer ends of The inner ends ofthe rods'12 have threaded thereon'bushings or sleeves 'which, to-

.gether with the rods 12 are provided with holes for the reception of the ends of coil springs 16 which have their other ends engaged within the holes in the extensions 10 of the disk 9. Collars 17 are disposed upon the outer ends of the tube 8 and have their horizontal flanges secured upon the tube by screws 18 which through the tube and into the plugs 11 pass through the flanges whereby the plugsll are held within the tube 8. Cable'drums or spools 19 are loosely mounted upon the tube 8. adjacent its ends and are a-djustably secured in relation there to by means of screws 20 which pass through the drums and engage within selected ones of a plurality of holes 21 formed in the verticalflanges 22 of the collars l7.

In order that the shade'roller 23 may be vertically movably mounted upon the win dow frame 5 I provide guides24c secured upon the window frame below and in alinement with the drums 19; Each of these guides comprises an upper head 25 secured upon the window frame as at 26 and provided with a circular recess 27 and a hole '28 through its upper portion communicating with the recess. A tube 29 preferably cirwhich "extend upwardly and are trained .lar tubes 29 and thevfiat plate portions'extending through slots 39 formed in the front cular in cross section has its upper end disposed within the recess 27 and its lower end disposed within the recess 30 in a lower head 31 secured upon the window frame as at 32. The head 31 has a hook 33 formed thereon for a purpose to be described. 7

l The shade supporting means comprises a pair of brackets 34, one provided with the usualslot 35 for the reception of the squared end of the projection on one end of the shade roller 23, and the other provided with the usual circular hole for the receptionof the pin upon the other end of the shade roller.

The brackets 34 are provided with heads 36 provided with longitudinal openings 37 through which extend cables or cords 38 about the drums 19. The brackets 34 are mounted relatively to the guides 24 by hav ing the heads '36 disposed within the circu of the tubes. It will thus be seen that the brackets 34 are vertically slidable within the tubes. a j

' In order that the shade roller 23 may be pulled down I provide an ear 40 upon one of the brackets 34 through which is secured one end of a chain 41 having a plurality of rings 42 secured thereon. When the shade I roller is pulleddown any one of the rings 42 may be engaged upon the hook 33.

The device is applied to a window by inserting the squared portions 13 within the slots 14 in the brackets 6 whereby the spring 7 roller 7 will be supported and the outer ends of the springs 16 will be held stationary; As the plugs 11 are revoluble upon the smooth shanks of the rods 12 the springs 16 19 are then secured to the collars 17 by inserting the screws 20 through the drums 19 and into the proper holes 21 in the flanges .22 of the collars 17. The shade roller 23 will then be held'firmly in its highest position as the cables 38 pass through the openings 37 in the shade roller supporting brackets 34 and are knotted thereunder. hen the chain 41 is pulled to-lower the brackets 34 the springs 16 are put under greater tensi n'so that when the rings 42 are released from the hook 33 the tension of the springs will rotate the tube 8 and conse- 19 which will then wind up the cables 38. and return the shade to its original position. If it is desired at any time to vary the tension of the springs it is asimple matter to claim: a V V 1. A device ofthe character described do so as it is merely necessary to remove the screws 20 and insert them indiflerent holes 21 in the flange 22 of the collar 17. 7

It is to be observed that my device does not in any way interfere with the action of the shade which, is absolutely independent of frame for allowing proper ventilation with-- in a room. 1 V

It will be readily understoodthat I reserve the right to make various changes in the form, construction, arrangement and combination of parts without departing from the spiritlof the invention or limiting the scope ofithe subjoined claims.

Having .thus described my, invention, II

comprising a springroller provided upon its ends with collars rigidly secured thereto and provided with a'plurality of holes, drums mounted on said spring rollerlandrevolubly slidably engaged by shade roller supporting adjustable thereon by the engagement of screws within selected ones of said holes,

brackets disposed below said drumsand said curtain V roller brackets for moving them downwardly, said movable brackets 7 'being returnable by the tension of said spring roller. I e e a 2. In a device of the character described, a sprlng roller comprislng a tubular memupon the ends of said tubular member and providedupon their peripheries with a plurality of holes, drums mounted on said tubularmember, and screws passing through 'ber provided at its center with a disk, plugs saiddrums and engagingselectedones of 7 the holes in said last named collars, whereby the tension of the springs may be varied by rotation of said tubular member after the removal or" said -screw.without removing sald rods fromsald supporting brackets.

3. In a dev ce of the character described,

a'sprin'g roller,con1'prising"atube,"a disk securedwlthin and at the central portion of said tube, a plug securedwithin each end of said tube and provided with an opening,

a rod revoluble through each of said openings and provided atits outerv end with a squared headiengageable with a bracket, a spring connecting saiddisk with the inner end of each of said rods, a flanged collar secured upon each end of said tube and provided with a plurality of transverse holes, a winding drum mounted on each end of said tube, and a screw extending through each drum and through a selected one of the holes in each collar, whereby upon removal of said screws said tube may be rotated to vary the tension of said springs Without shifting the position of an article suspended 10 by flexible members trained about said drums.

In testimony whereof, I aflix my signature, in the presence of two Witnesses.
